WETTING ATTACHMENT FOR TRIMMING-MACHINES.

Specification of Letters Patent.

Patented May 29, 191?.

Application filed September 11, 1916. Serial No. 119,421.

To all whom it may concern:

Be it known that I LAWSON D. IIILTZ, a subject of the King of Great Britain, residing at Marysville, Province of New Brunswick Canada, have invented certain new and useful Improvements in Wetting Attachments for Trimming-Machines; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to wetting attachments for trimming machines where in the edge of the sole of the shoe is dampened before the last out is made. An object of the present invention is to provide an attachment for the ordinary trimming machine which may be easily and readily applied thereto and when in use will eliminate hand labor and former hand methods of spraying the moisture, thereby entirely doing away with the disadvantages which occur in cutting operations upon edge trlmming machines.

With the above and other objects in view which will hereinafter appear as the description continues, the invention consists of the novel features of construction and the formation of parts as will be hereinafter more fully described and particularly pointed out in the appended claims.

In the accompanying drawings is shown the simple and preferred form of the invention it being, however, understood that no limitation is necessarily made to the precise structural details herein exhibited but the right is hereby reserved to any changes or alterations that may be had and come within the scope of the invention without departing from the spirit thereof or sacrificing the efficiency of the same.

In the accompanying drawings;

Figure 1 is a detail side elevation of a trimming machine having the attachment as applied thereto;

Fig. 2 is an'end elevation; and,

Fig. 3 is a vertical section through the attachment.

Referring now more particularly to the accompanying drawings wherein like and corresponding parts are designated by similar reference characters throughout the several views.

In the drawings the letter A indicates an ordinary edge trimming machine having arranged in the bearings B thereof a driven shaft C which is driven by applying suitable power thereto and arranged upon the outer end of the shaft D is the revolving cutter or edge trimmer E.

The attachment forming the subject matter of the present invention is adapted to be rigidly secured to the support of the edge trimming machine having a dampener supported thereby and suspended over the cutter E whereby the dampener may travel upon the edge of the sole of the shoe and will pass over the edge of the sole of the shoe after the cutter has performed its first trimming operation upon the sole of the shoe so that the edge of the sole of the shoe will be thoroughly soaked with moisture before performing this second cut. Projecting from one of the bearings B is a projection 1 upon which is adapted to be placed a sleeve 2. This sleeve is provided with a central aperture so that the shaft C may pass therethrough and is also provided with an enlarged recess 3 for the reception of the projection 1. Arranged diametrically opposite within the sleeve 2 are the L shaped slots 1 in which are adapted to rest the pins 5 extending from the projection 1, so that when the sleeve 2 is placed upon the projection 1 it may be fastened thereto by means of these slot and pin connections. Adapted to be placed over the sleeve 2 is a casing 6 having diametrically opposite adjustable screws 7 arranged therein and the inner ends of these screws are adapted to rest within the segmental slots 8 formed within the outer periphery of the sleeve 2 whereby the outer casing can revolve a short distance upon the sleeve 2. An arm 9 is connected to the casing 6 by means of the set screw 10 and the outer end of this arm has secured thereto a casing 11. This casing 11 has an inlet opening 12 leading thereto and in communication with this inlet opening is a rubber tube 13 whereby water or other suitable liquids may be supplied to the casing 11 from the tank 14. A valve 15 is also provided for controlling the flow of the liquid from the tank 14 to the casing 11. Projecting from the casing is a pair of arms 16 and adapted to be retained be tween these arms 16 is a moistener 17 preferably made of felt but may be of any liquid absorbing material desired. The body portion of this moistener is retained between the arms 16 having its inner end projecting Within the casing 11 and its outer end projecting over the extreme outer ends of the arms 16; The casing 6 has secured to the outer periphery thereof a weight 18 which causes the casing 6 to turn upon the sleeve 2 so that the moistener 17 will nor-- mally rest in its lowermost position, but this position is limited by means of the slot and pin connections indicated by the numerals 7 and 8 respectively for a purpose which will be later described.

Extending from the frame of the trimming machine is an arm- 19 having pivotally connected at its upper end a lever 20. One end of this lever 20 is connected to the casing 6 by means of a chain 21 or any other suitable flexible connection, whereas a cable 22 is connected to the opposite end of the arm 20 and the loWer end of this cable 22 may be connected to a foot pedal whereby upon pulling down upon the cable 22 the casing 6 may be oscillated, but when the cable 22 is released the weight 18 will cause the casing 6 to oscillate inan opposite direction, due to gravity.

From the foregoing it is obvious that the trimming machine may be used for trimming the edges of the soles of shoes in the usual manner, and as the sole is being trimmed for the first time the dam-pener 1? will follow directly behind the cutter and thoroughly moisten the trimmed portion of the sole' of the shoe, and by the time the operator is ready to perform the second out upon the sole of the shoe the moisture will thoroughly soak Within the sole of the shoe permitting the same to be in condition to be again cut. During the second cutting operation it is not necessary to again dampen the edge of the sole'of the shoe, and the operator can exert a force upon the cable 22 causing the casing 6 to oscillate upon the sleeve 2 thereby holding the moistener out of contact with the sole of the shoe; By permitting the casing 6 to oscillate upon the sleeve 2 the moistener will be permitted to give due' to the irregularities upon the edge of the shoe sole but the weight 18' will force the moistener incon tact with the edge of the shoe sole;

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. The combination with a trimming machine of a casing mounted thereupon, a

moistener carried by said casing, and means whereby said casing may be oscillated for the purpose set forth.

2 The combination with a trimming machine, of a casing arranged thereupon, means for oscillating said casing, an arm extending from" said casing, and a moistener carried by the outer end of said arm for the purpose set forth.

3. The combination with a trimming machine having a bearing, shaft journaled within said bearing anda cutter carried by the outer end of said shaft, of a: sleeve detachably secured to said bearing,- a casing arranged to oscillate upon said sleeve, an

mounted upon said sleeve, anarmproj ecting from said casing, a moistener carried by said arm, a supply tank, and a] flexlble connection between said supply tank and said moistener for the purpose set forth.

5. The combination with a trimming machine comprising a bearing having a shaft journaled therein and a cutter carried by the outer end of said shaft, of projection carried by said bearing, a sleeve detachably connected to saidp'r'ojecti'on, a casing mounted uponsaid sleeve, slot and pin connections betweensaid casing and said sleeve for permitting the casing to oscillate upon said sleeve, a weight carried by said casing for causing the casing to turn in one direction, an arm carried by said casing, a moistener' carried by said arm, and means connected to said casing for causing the same to turn in an opposite direction to that iniwh-ich the weight is adapted to cause the casing to turn substantially as and for the purpose specified;

In witness whereof I have hereunto set my hand. I

LAWSON D1 HILTZ.
